I was extremely worried before my first appointment about same thing and about not finding a heartbeat. On Tuesday I had my first ob appointment and I was so surprised and excited about seeing my baby for the first time he/she wouldn't stop moving and waiving arms even the dr. Screaming omg omg!! All my fears went away and now I'm a million times more excited I'm 11 weeks...don't sweat it your baby will be just fine congrats! c:
Birth defects are actually pretty rare. I caught myself worrying about that alot too. Until I realized how rare and unlikely it was. But trust me when I tell you to please just enjoy this pregnancy and have faith that everything will be ok. Worrying so much takes away from all the joy you should have. I worried way too much and I look back and wish I hadn't. Theres nothing we can do other than take good care of our body, eat healthy, see our ob, and have faith. Your baby will be perfect no matter what :)
Don't think about the negative I know it's easier said than done but don't scare urself and put all these bad things in ur head .
